Fine Grade. The glass is COE 104
Aether is a colorless encasing glass designed for superb workability in the flame. It is engineered to be resistant to boiling, free from seed bubbles, and handled with the utmost care to ensure freedom from scratches and dust. In other words, it is our clear.
Aether does contain certain chemical components that can react with metallic silver and cause a reaction. These chemicals also keep Aether remarkably free of seeds, and help to preserve the metallic sheen of the encased silver. The reaction often appears as a yellow/green tint. Working the encased bead hot often increases this effect. If you want to avoid that reaction entirely, we recommend Zephyr clear instead.
The frit is run through a magnet trap to remove any metal particles from the crushing equipment and is then washed to remove the glass powder
